Big Dig using more RAM than allocated

[Stone Rhino]

I'm starting to think java 1.7_21 has a horrible memory leak. I can play for about 30 minutes creative, or 1 hour in survival mining until RAM usage exceeds the imposed limit and CPU usage spikes to 100% on all 8 cores. The client will stop functioning until MC flushes its cache and everything's great for 30 seconds. Then I glitch into a wall, suffocate and die. This is happening for multiple users on my server.

I open task manager and perfmon and can clearly see the swapfile is heavily active. Also I can see java.exe pulling far more than I tell it.

Did you try Java 7v25?

Will check that, but Ive had this problem before with other pure JRE apps. I'll run thing through the wash tomorrow. Just got back into town.

Update java. Simple as that

Still does it with 1.7 u25.

Every time it goes to flush the buffers it jams the cpu up, freezes the game for 10 seconds and its fine for 15-20 seconds. Cycle repeats. Have to quit the game, and come back.

Uninstall Java completely, reboot PC, Install Java 7 u25 64bit, reboot again. That fixed it for me. Java seems to be quite a bitch when updating and seems to forget some of its files.

Otherwise try TBD 1.3.13, personally I think its more stable than 1.3.9.

Also, what is very strange is that this is an intermittent problem. One day it happens incessantly. Yesterday, not a peep at all! Nothing different. So infuriating.
